some are versioned. By using shared and versioned layers of mounts it

is easy to update jails in a new version while the current version is

still running, you can switch back to an older version of a jail.

Most of the layers are mounted read-only for security reasons.

Let's take a look at the layers of a typical running jail built with `jaildk`:

|
```

|
||||||
|
|
|
||||||
|
+--- root of the jail
|
||||||
|
```
|
||||||
|
|
||||||
|
As can be easily deduced this is a database jail with the following layers:
|
||||||
|
|
||||||
|
1. **base layer**: This is basically the same as a FreeBSD base, which
|
||||||
|
contains all biinaries, libraries and other files required to boot
|
||||||
|
up a FreeBSD system. Our base doesn't contain a kernel by default,
|
||||||
|
but you could add one, required if you want to use the ports
|
||||||
|
collection and compile `lsof` yourself.<br/>
|
||||||
|
This particular base is based on 12.1-RELEASE-p10, that is, I
|
||||||
|
created it while I had this release installed and running on the
|
||||||
|
host system.
|
||||||
|
2. **tmp layer**: Just a ramdisk for `/tmp`, the size can be tuned.
|
||||||
|
3. **dev layer**: Contains /dev/null and friends, required by every jail.
|
||||||
|
4. **log layer**: Here we have our first versioned layer for
|
||||||
|
`/var/log`. Notice how all other layers are using the same version,
|
||||||
|
this is done by purpose (but can be changed if you like). The
|
||||||
|
version is a jail variable (see below) which is being used for all
|
||||||
|
layers.
|
||||||
|
5. **application layer**: As you know if you're using FreeBSD, any
|
||||||
|
additional software, wether installed from a port or as package,
|
||||||
|
will be installed to `/usr/local`. In our case it contains the
|
||||||
|
mysql server software, bash and a couple of supporting
|
||||||
|
utilities. It is being mounted read-only, so no new software can be
|
||||||
|
installed in the running jail. This might sound annoying at first,
|
||||||
|
because you can't just install stuff inside the jail anytime you
|
||||||
|
like. But it forces you to work more disciplined. Once a jail has
|
||||||
|
been completely built you can be sure, all components match with
|
||||||
|
each other. Read below how to install or update software in a jail.
|
||||||
|
6. **/etc layer**: this just contains the normal etc, it is basically
|
||||||
|
a stripped copy of the host `/etc`. We do not use it at all inside
|
||||||
|
a jail, but it's required nontheless. There are some exceptions
|
||||||
|
however, like `/etc/resolv.conf`.
|
||||||
|
7. **/usr/local/etc layer**: This is the place we configure all
|
||||||
|
aspects of the jail, all configs reside here (like in our case the
|
||||||
|
mysql config). It is also being mounted read-only, just like
|
||||||
|
the etc layer.
|
||||||
|
8. **cron layer**: A writable mount for the crontabs of users inside
|
||||||
|
the jail. That way one can modify crontabs with `crontab
|
||||||
|
-e`. However, if you don't want or need this, just remove the layer
|
||||||
|
and add cronjobs to `/etc/crontab`.
|
||||||
|
9. **/root layer**: most of the administrative work inside a jail must
|
||||||
|
be done as the root user and it would be a pity not to have a
|
||||||
|
writable history. So, `/root` is mounted writable to add more
|
||||||
|
comfort.
|
||||||
|
10. **a data layer**: A versioned data layer which contains the binary
|
||||||
|
data of our mysql server. This is very jail specific and you have
|
||||||
|
to add such layers yourself. Variants of such a layer include the
|
||||||
|
document root of a webserver or the repositories of a git server.
|
||||||
|
11. **backup layer**: Another custom layer, here we've mounted a
|
||||||
|
global backup directory of our host which contains all backups.
|
||||||
|
|
||||||
|
All layers are configured in a `mount.conf` file specific for each
|
||||||
|
jail. The one for this jail looks like this:
|
||||||
|
```
|
||||||
|
base/$base $name nullfs ro
|
||||||
|
md $name/tmp mfs rw,nosuid,async 500m 1777
|
||||||
|
dev $name/dev devfs
|
||||||
|
log/$name-$version $name/var/log nullfs rw
|
||||||
|
appl/db-$version $name/usr/local nullfs ro
|
||||||
|
etc/$name/etc-$version $name/etc nullfs ro
|
||||||
|
etc/$name/local-etc-$version $name/usr/local/etc nullfs ro
|
||||||
|
etc/$name/cron-$version $name/var/cron nullfs rw
|
||||||
|
home/$name/root-$version $name/root nullfs rw
|
||||||
|
data/$name/mysql-$version $name/usr/local/data/mysql nullfs rw
|
||||||
|
/backup/db $name/var/backups nullfs rw
|
||||||
|
```
|
||||||
|
|
||||||
|
Now, as you can see, we're using variables here. Those are defined in
|
||||||
|
the `jail.conf` (not to be confused with `/etc/jail.conf` on the
|
||||||
|
host!):
|
||||||
|
```
|
||||||
|
name=db
|
||||||
|
version=20201026
|
||||||
|
base=12.1-RELEASE-p10
|
||||||
|
```
|
||||||
|
|
||||||
|
You might wonder how the other aspects of a jail are configured like
|
||||||
|
ip addresses, routing, jail parameters, sysctls etc. Well, that's
|
||||||
|
beyond the purpose of `jaildk`. You just use the standard FreeBSD
|
||||||
|
mechanism for these things, that is `/ect/rc.conf`, `/etc/jail.conf`,
|
||||||
|
`service jail ...`, `jexec`, etc. However, `jaildk` provides some
|
||||||
|
handy wrappers to make live easier.

## Advanced Features
|
||||||
|
|
||||||
|
Jaildk also offers some advanced features like automatically setting
|
||||||
|
up and deleting ipfw rules or freezing and thawing a jail (to make it
|
||||||
|
easily portable).
|
||||||
|
|
||||||
|
### Using the IPFW
|
||||||
|
|
||||||
|
To use the IPFW on your host you first have to enable ipfw in your
|
||||||
|
hosts rc.conf `firewall_enable="YES"`. You probably want to set the
|
||||||
|
default firewalling-type there aswell, check out the
|
||||||
|
[FreeBSD handbook](https://www.freebsd.org/doc/handbook/firewalls-ipfw.html)
|
||||||
|
for further information.
|
||||||
|
|
||||||
|
Once enabled you also need to start ipfw by executing the rc script:
|
||||||
|
|
||||||
|
`/etc/rc.d/ipfw start`.
|
||||||
|
|
||||||
|
Be aware that inter-jail communication is transfered via the loopback
|
||||||
|
interface (normally lo0) for which there is a high priority allow any
|
||||||
|
to any rule by default:
|
||||||
|
|
||||||
|
`allow ip from any to any via lo`
|
||||||
|
|
||||||
|
In order to control the inter-jail communication you have to delete
|
||||||
|
this rule first.
|
||||||
|
|
||||||
|
If an ipfw.conf exists for a jail (e.g. /jail/etc/myjail/ipfw.conf)
|
||||||
|
the rules inside that config file are added when starting, and deleted
|
||||||
|
when stopping the jail. E.g. allowing HTTP/HTTPS traffic for that
|
||||||
|
jail (webserver):
|
||||||
|
|
||||||
|
`allow tcp from any to $ip setup keep-state`
|
||||||
|
|
||||||
|
As demonstrated in the previous rule `$ip` is reserved and
|
||||||
|
automatically replaced with the jails own ip (as reported by
|
||||||
|
`jls`). The same applies to the ipv6 address which will be available
|
||||||
|
as variable `$ip6`. Also, all variables in the jails `jail.conf` can
|
||||||
|
be used.
|
||||||
|
|
||||||
|
In order to make these ipfw rules available on boot, you need to add
|
||||||
|
the following line to `/etc/jail.conf` in the section of the jail
|
||||||
|
which uses custom ipfw rules:
|
||||||
|
|
||||||
|
`exec.prestart = "/jail/bin/jaildk ipfw $name"`
|
||||||
|
|
||||||
|
Be aware, that the ipfw module will only be executed if the jail is
|
||||||
|
running so that we can properly determine the ip addresses of the
|
||||||
|
running jail. **Note**: this might change in the future.
|
||||||
|
|
||||||
|
### Using pf
|
||||||
|
|
||||||
|
Beside ipfw, Free supports
|
||||||
|
[pf](https://www.freebsd.org/doc/de_DE.ISO8859-1/books/handbook/firewalls-pf.html)
|
||||||
|
as well. You can use pf with `jaildk`. Unlike the ipfw module (see
|
||||||
|
above) it is a normal `install` module. That is it can be installed or
|
||||||
|
reloaded before the jail is running (i.e. like the mount module).
|
||||||
|
|
||||||
|
In order to use `pf` with a jail, enable and configure it according to
|
||||||
|
the FreeBSD handbook linked above. It is recommended to include
|
||||||
|
general block, scrup, state rules, communication to and fro localhost
|
||||||
|
etc and just leave everything which is related to your jail.
|
||||||
|
|
||||||
|
Just so that you know how such a global `/etc/pf.conf` file might look
|
||||||
|
like, here's a simple one:
|
||||||
|
```shell
|
||||||
|

|
||||||
|
Install the ruleset with `service pf start`.
|
||||||
|
|
||||||
|
Now that everything is prepared you can create a `/jail/etc/myjail/pf.conf` file for your
|
||||||
|
jail. Here's an example I use for a webserver jail, which includes a
|
||||||
|
git server:
|
||||||
|
```shell
|
||||||
|
ip = "jail ip4 addr"
|
||||||
|
ip6 = "jail ip6 addr"
|
||||||
|
loginports = "{ 22 }"
|
||||||
|
prodports = "{ 80, 443 }"
|
||||||
|
ext = "em0"
|
||||||
|
|
||||||
|
# dynamic block list
|
||||||
|
table <blocked>
|
||||||
|
|
||||||
|
# restrict foreigners
|
||||||
|
block quick from <blocked>
|
||||||
|
pass in quick on $ext inet proto tcp from any to $ip port $loginports \
|
||||||
|
flags S/SAFR keep state \
|
||||||
|
(max-src-conn-rate 10/60, \
|
||||||
|
overload <blocked> flush global) label ServicesTCP
|
||||||
|
|
||||||
|
# allow production traffic v4
|
||||||
|
pass in quick on $ext proto tcp from any to $ip port $prodports keep state
|
||||||
|
|
||||||
|
# allow production traffic v6
|
||||||
|
pass in quick inet6 proto tcp from any to $ip6 port $prodports keep state
|
||||||
|
```
|
||||||
|
|
||||||
|
That's it already. Now install the jail as usual. You can also install
|
||||||
|
the pf ruleset for the jail separately:
|
||||||
|
|
||||||
|
`jaildk install myjail start -r pf`
|
||||||
|
|
||||||
|
To take look at the rules, execute:
|
||||||
|
|
||||||
|
`jaildk install myjail status -r pf`
|
||||||
|
|
||||||
|
You can of course manipulate the ruleset manually. `jaildk` installs
|
||||||
|
rulesets into a jail specific anchor using the following naming
|
||||||
|
scheme: `/jail/<jail name>`. So, for example to view the rules, execute:
|
||||||
|
|
||||||
|
`pfctl -a /jail/myjail -s rules`
|
||||||
|
|
||||||
|
Manipulate a jail specific table:
|
||||||
|
|
||||||
|
`pfctl -a /jail/myjail -t blocked -T show`
